Application iledl September 14, 1927. VSerial No.7219,444..

n' f Theprimaryobjectof'this'invention is to provide a hopper for generaluse, but particularly for receivingfandf discharging garbage and otherrefuse mto a chimney flue for inthe basement of 'an apartment l house. 1 l

`Asecor'id object is to provide such a device which will catapultv the garbage or refuse into the chimney flue' without depending upon the I gravitation of the same into the chimney flue. f Y A third object is to avoid the presence of v pockets inwhichburning embers, soot and the like may accumulate to later be forced into Y 15 the room by the draft caused by the opening of the hopper door forthe vdeposit of refuse, this 'being avoided by the provision of a closure substantially flush with the inner facey of thechimney flue, thereby also avoiding the means whereby leakage of' smoke, fumes and l the like into the room will be avoided by quick acting automatic closing of the opening into the chimneyl ue when the hopperfis'in its openor closed position. j

f A still further object isA to avoid the presence of projections into the chimney flue to interfere with and-r'educethe draft.

3() Withthese and other importantv objects in View, reference will be had to the accompanying drawing which forms a partl of this speciwith the parts in built a: metal flue-box comprising a horizontal.

topvwall, parallel verticalv side walls 4 at right anglesftothewall 3, anddownwardly convenience in installing the hopper'in' place,

afoot 6 isprovided on the' lower outer side of the bottom wall5. The back of the flue-box andrearwardly sloping bottom wall-5. g For "isrop'en; except'fort a depending flangefor back plate 7 alinged'withwhich is a flange 8 tofaid in anchoring'the flue-box in the wall. The walls 3, 4 and 5, terminate substantially in the plane of the front face of the wall 2 and receive the door frame, which consists of areotangular plate 9, provided with a chargingv opening 10 surroundedby a'rim 11. This'rim is beveled upwardly and rearwardly and is closed by an inclined door 12 having a marginal flange 14 which engages 4over thesaid rim 11 of the door frame plate 9. The vdoor frame plate'9 is mounted in place,'aft er the plastering is applied to the wall`2, by screws 15 which passthrough said plate 9into threaded ears 16 provided on the side walls 4 of the flue-box. The door 12 is provided with perforated ears 17 which are pivoted bypintle means 18`to ears19 provided on the outerside of the bottom wallof the rim 11, a handle 20 being provided for opening and closingfthe door 12. i l f The vinner side of the Adoor 12 is provided'.

with ay joint closing plate or flange 21 which engages thev upper outer edges of the lower j wall of the rim 12 when the door is opened to prevent smoke, odors andthe like from passing through this joint into the room.v A pair of parallel side walls122 are attached to the inner face of the door 12and ends of the plate or flange 21` and extend inwardly a considerabledistance, hugging the side walls 4 of the-'flue-boxl closely to prevent kvleakage-of smoke, odors and the like into the room. The.l

rear free ends of the walls'22 are bridged by a bar24 and held thereby against displacement, and upon this bar 24 is hingedly mounted the `hopper scoop bottom plate 25. This plate '25isbowed s'o as to -form a cuppedv garbage receiving element when the door is j opened," at which time, the forward edge V26 engages the inner face of the door 12,-while the opposite end 27- engages the lower edge of the flange 7 preventing, withthe Vother parts v described, the passage' ofsmoke and odors into/thev room. f f

Adjacent its side edges, the hopper scoop bottom plate 25 is provided on its under side (open position) with rocker flanges 30, which, when the door is moved toward closing position, ywill move downwardly-into engagement with the inclined wall 5 and cause the hopper scoop bottom plate 25 to swing to the position inFig. l with its edge 26 engagedl with the inner face of the Harige 7, causing the garbage that was deposited on said plate 25 to be automatically'dumped into the chimney, falling down the same to the incinerating grate, not shown, but in common use.

It will be understood that in apartment houses where one or more hoppers are installed for each Hoor, that any leakage through the joints of the hopper will be multiplied by the number of hoppers on that Hooi' plus the hoppers on the other floors, so that however small the leakage might be at any one hopper, when multiplied by the total number of lioppers, the total leakage may be considerable and so great as to cause material draft trouble.V 'Io avoid such, leakage and to reduce the saine to a minimum, this invention is provided, and it will be seen that when the door 12 is opened for the deposit of garbage, that the movement of the pintle bar 2a upwardly will cause the hopper scoop bottom plate 25 to quickly fall to its receiving position (Fig. 2) and directly thereafter, the end 27 engages the flange 7 and with the other parts closes the opening into the Hue. Then, upon closing the door, the'rocker engaging the bottom 5 as aforementioned, causes the hopper scoop bottom plate 25 to swing to its vertical (Fig. l) position, catapulting the garbage into the chimney Hue, and preventing the adherence of any of the garbage to such plate. When in its vertical position, the opening into the chimney Hue is closed not only thereby, but further sealing is effected by the door 12 being closed; AThis not only gives protection against the .annoyance of smoke and objectionable fumes entering the room, but gives assurance against the accumulation of burning embers lodging in the usual hopper pockets and later entering the room, this in itself being a great fire proteogtion.

What is claimed L- l. The combination with a Hue, of a hopper vhaving relatively movable members for automatically positively closing the passage into the Hue when the hopper is in its full open and closed positions, and means for moving one of said members relatively to the other for catapulting the hopper contents into the Hue.

2. A device of the character described, coniprising a housing having spaced walls, and a receiving member pivoted in said housing and includingrelatively movable front and rear members, the front member being adapted to engage one of said walls in closed position and the opposite end of the rear ineinber being adapted to engage the other of said walls in open or closed position. Y

3. A device of the character described, comprising a housing having spacedr front and Vmovement of said'door into engagement housing, a door hinged to the front side thereof, and a bottom member carried by said door 'and automatically Y movable upon opening movement of said door into engagement with said door-and a'rear portion of said housing, and automatically movable upon closing1 y wit a rear portionof said housing,V f
